A PHP class to analyse a string of CSS to produce statistics. It is able to get the following information about a string of CSS:
- Number of rules
- Number of selectors
- Number of media queries
- Number of property definitions
- Size (in bytes)
The class assumes that your CSS is valid - always run your code through a CSS Lint tool first.
You can see a demo of the class in action at: www.cssanalyser.com.
Use Composer - simply css_analyser to your composer.json file:
{
"require": {
"gbuckingham89/css_analyser": "dev-master"
}
}
Simply download and extract the ZIP into your project and include the class (css_analyser.php) using require() or include() in the most appropriate place for your project.
Input CSS and return all of the results as an array:
$css_string = ".example-css { color: red; }";
$analyser = new \gbuckingham89\css_analyser();
$results = $analyser->process($css_string);
Or, if you only need one or two or the results, simply call the relevant m ethod:
$css_string = ".example-css { color: red; }";
$analyser = new \gbuckingham89\css_analyser();
$analyser->process($css_string, false);
$number_of_rules = $analyser->get_rules_count();
$size = $analyser->get_size();
